Average pH of surface waters in 1850 and 2100

Average pH of surface waters in 1850 vs its projected value in 2100 if current trends continue; CO2 emissions have increased ocean acidity by 26% since the beginning of the industrial revolution, by 2100 the acidity will have surged by 170%; as a result, many marine species will become extinct.

Average pH of surface waters in 1850 and 2100

- It's essential to note that the pH scale is logarithmic, i.e. a pH of 6 is ten times more acidic than a pH of 7 and 100 times more acidic than a pH of 8. That's why a decrease from 8.2 to 7.8 is a drastic change for the oceans.

- Why and how does ocean acidification happen? About 30% of the carbon dioxide emitted in the atmosphere is absorbed by the global ocean. Once CO2 meets the H2O, we get: 1. carbonic acid H2CO3 and 2. free hydrogen ions H+. Now, these free hydrogen ions H+ will bond with carbonate ions CO3(2-), which is bad, because carbonate ions are essential for the creation of calcium carbonate CaCO3, an essential ingredient for calcium based structures such as shells and coral. Basically too many H+ in the ocean, an effect of CO2 emissions, is stealing all the CO3(2-), which is fundamental for many marine species.


- Why is this important for humans? Around 70% (estimates vary from 50% to 85%) of the oxygen is produced by marine plants. Primarily by phytoplanktons. If ocean acidification continues, many species will suffer drastic consequences (some of them will inevitably become extinct), including phytoplanktons. Their balance will be greatly disturbed, many phytoplankton species will migrate and maybe adapt to the new conditions, others will probably dissapear. This will in turn reduce global oxygen levels. Fun fact: Phytoplankton population dropped by 40% since 1950.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

Moose population in North America

The moose ( Alces alces ) is the largest member of the deer family, characterized by its massive size, long legs, and distinctive broad, palmate antlers found in males. They have a dark brown or black coat and a humped shoulder. Moose are primarily found in the boreal and mixed deciduous forests of North America, Europe, and Asia. They are solitary animals, often found near bodies of water, and are herbivores that feed on leaves, bark, twigs, and aquatic vegetation. Despite their size, moose are strong swimmers and can run up to 35 miles per hour. The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North American moo

Map of Fox Species Distribution

Foxes are small to medium-sized members of the Canidae family, which also includes wolves, dogs, and other related animals. There are about 37 species of foxes distributed around the world, and they inhabit a wide range of environments, from forests and grasslands to deserts and urban areas. Below is the map of fox species distribution  created by Reddit user isaacSW Here are some of the most well-known fox species and their distribution: Red Fox ( Vulpes vulpes ): The red fox is one of the most widely distributed fox species and is found in North America, Europe, Asia, and parts of North Africa. They are adaptable and can live in a variety of habitats, including forests, grasslands, and urban areas. Arctic Fox ( Vulpes lagopus ): The Arctic fox is found in the Arctic regions of North America, Europe, and Asia. They have adaptations that help them survive in cold climates, such as a thick coat that changes color with the seasons. Gray Fox ( Urocyon cinereoargenteus ): The gray fox
